Measure Commands

:MEASure:CDRRATE

Command
:MEASure:CDRRATE <source>
The :MEASure:CDRRATE command determines the data rate (clock
recovery rate) from the clock recovery method being used. It yields one
data point per acquisition so trending cannot be performed on this
measurement.
<source> {CHANnel<N> | FUNCtion<F> | WMEMory<N> | CLOCk | MSPectrum |
MTRend | EQUalized}
MTRend and MSPectrum sources are only available if the oscilloscope has
the EZJIT option installed and the feature is enabled.
The CLOCk source is only available if the oscilloscope has the High Speed
Serial option installed and the feature is enabled.
The EQUalized source is only available if the oscilloscope has the High
Speed Serial option and the Serial Data Equalization option installed and
the features are enabled. This command uses the Feed- Forward Equalized
(FFE) signal as the source.
<N>
CHANnel<N> is an integer, 1- 4.
WMEMory<N> is an integer, 1- 4.
<F>
FUNCtion<F> is an integer, 1- 16.
Example This example measures the clock recovery rate of channel 1.
myScope.WriteString ":MEASURE:CDRRATE CHANNEL1"
Example This example places the current data rate of the channel 1 waveform in
the numeric variable, varValue, then prints the contents of the variable to
the computer's screen.
myScope.WriteString ":SYSTEM:HEADER OFF"
myScope.WriteString ":MEASURE:CDRRATE? CHANNEL1"
varValue = myScope.ReadNumber
Debug.Print FormatNumber(varValue, 0)
